[GENERAL] Migrating from 8.2 to 9.1 : invalid port number

[Alberto Zanon]

Hi all, 

in my production environment I have Postgresql 8.2 + PgPool. The port number I 
specify in PgPool configuration is not a real portnumber (e.g. 123456). I can 
define a "dblink" as : 

dblink('dbname=XXXX host=/var/run port=123456 user=XXXX password=XXXX'::text, 
'select ... '::text) t1( ... ); 

or start "psql" as: 

psql -U XXXX -h /var/run -p 123456 XXXX 

without problems. In my development environment I upgraded to 9.1 version and 
the result is: 

invalid port number: "123456" 

in both cases. Does Postgresql 9.1 check the "port number" value although I'm 
connecting through a "Unix domain socket"? Is it a bug or an intended behavior? 
I noticed that it accepts values up to 65535 . 


Thanks in advance 

Alberto
